ST example uses 400MHz / 4 = 100MHz for SDRAM. What should the SDRAM clock be when the system is running at 480MHz? If we use 480/4 then it is 120Mhz for SDRAM, but datasheet shows max of 100MHz for SDRAM! Are we stuck running SDRAM at 60Mhz? Or run ...
Hello.I would like to use the STM32G0B0RE to write and read about 1KB of text data from an STM microcontroller to a USB memory device.When I looked for sample code to do this, I could not find any.So is there some kind of beginner's guide for writing...
Hello,We have designed a board around a STM32G0B1CB where almost all the 48 pins are used for different stuff (lots of analog inputs, communication and PWM).It is not our first design with STM32 uC, but we are facing an issue here and I would like to...
Hi ,I am trying to use 2 usart in stm32wl. But right now I am using Single uart which default PA2 and PA3 we can access through debug port, But I am trying to use through other gpios or pins through ttl But the output is not coming in terminal if I c...
I am trying to use the onboard DAC to generate a sine signal. The program runs without any problem on the Nucleo L432KC board but it would not work on our PCB with L431. As soon as the DAC is enabled with LL_DAC_Enable(DAC1, LL_DAC_CHANNEL_1); the pr...
I am using the STM32F746VET6. I am aware that assembly instructions do not have a guaranteed in execution time, however I am surprised how consistently inconsistent my inline assembly macro is behaving. I'm really hoping there is just a mistake in th...
Hi,I have some problems with LwIp on custom board. Cpu type - stm32h723vgh6, ethernet chip - adin1200ccpz.Phisical layer works fine (link led is up). I've generated cube project with UDP and ICMP support according to recommendations in example projec...
Dear AllI got the job to port a existing app which was developed for stm32h743 with 2mb flash to a stm32h750 with 128kb flash and a 8MB qspi memory.I basically succeeded in having a ext boot rom scenario where i would start from flash , enable qspi a...
tldr; Can I have a timer counter reset (once / one-shot) when the RX pin of a CAN-FD peripheral is activated, so I can later determine the exact time elapsed?I have a chain of ~8 STM32 devices on a ~2m CAN-FD bus. Several MCU part numbers (mostly G4)...
I'm working on STM32G491RET on the I2C bus. I've noticed intermittent noise on SDA and sparse timing inconsistency on the SCL as pictured. Could someone advise as to the nature/cause/imact of this.
